What are sexual and asexual reproduction?
1. Survival of a species depends on its ability to produce offspring.
2. Every organism comes from a parent through the process of
reproduction
3. The transfer of genetic material from parents to their offspring is
known as reproduction.
4. Genetic material contains the information that controls an organism’s
structure and function.
5. The production of a new organism from two parents is called sexual
reproduction.
6. When an egg cell joins with a sperm cell, fertilization occurs.
7. Egg and sperm cells are examples of sex cells.
8. A fertilized egg develops into an individual with traits from each parent.
9. The production of a new organism from a single parent is called
asexual reproduction. Offspring are identical to parent because they
have same genetic information.
How do organisms reproduce asexually?
10.
Most bacteria and unicellular protists reproduce by making a copy
of their genetic material and splitting.
11.
Cnidarians, sponges, and some fungi can reproduce through
budding.
12.
The eggs of insects, fish, frogs, and lizards sometimes develop into
new animals without being fertilized.
13.
New plants can grow from leaves, roots, or stems. This type of
asexual reproduction is called vegetative propagation.
14.
Strawberry plants and ferns can reproduce asexually by forming
runners. This is a form of vegetative propagation.
How do plants and animals reproduce?
15.
When plant and animals reproduce sexually, a fertilized egg
develops into an embryo.
Seeds and Fruits
16.
The fertilization takes place in the ovary of a flower.
17.
The embryo in a flowering plant develops in the seed.
18.
As the seed develops, the ovary enlarges to become a fruit.
19.
The development of a seed into a new plant is called germination.
Animal Eggs
20.
Animals that reproduce sexually begin as fertilized egg cells that
develop into embryos.
21.
The egg’s yolk provides food for a developing embryo.
22.
Reptiles and birds have eggs filled with a liquid and surrounded by
a tough shell so their eggs can be laid on land.
23.
The embryos of most mammals develop inside the mother.
24.
Monotremes are the only mammals that lay eggs.
How do fungi reproduce?
24.
Yeast reproduce asexually through budding.
25.
Eventually the bud breaks off and lives as a new, individual
organism.
26.
Multicellular fungi can also reproduce asexually.
27.
These fungi are made of tiny filaments called Hyphae. Hyphae
tangled together form mycelium.
28.
If you have ever walked through the forest and seen a mushroom
growing from the mycelium, this structure is called a fruiting body.
29.
Fruiting bodies produce spores which can grown into a new fungi.
How do sexual and asexual reproduction compare?
30.
An organism that reproduces asexually does not have to find a
mate.
31.
Organisms that reproduce asexually tend to be well suited to their
environments.
32.
A major advantage of sexual reproduction is that it promotes
variety in a species.
33.
Why is sexual reproduction better than asexual reproduction for
ensuring the survival of a species in a changing environment? During
sexual reproduction each offspring has a unique combination of
traits from both parents. This gives a better chance that at least some of the offspring
will be better adapted to a changing environment. During asexual reproduction the
offspring is genetically identical to the parent. Without variation, offspring may not be
as well adapted to a changing environment.
